。[Scope of Claim for Utility Model Registration] A commutator is fixed to the outer periphery of the shaft with a distance ring sandwiched between a rolling bearing that rotatably supports the shaft, and a bearing holder fixed to an end bracket is mounted on the outer periphery of the rolling bearing. A brush holder stay arranged to surround a commutator is fastened to the bearing holder, and a brush holder having a built-in brush that comes into sliding contact with the commutator is fixed to the brush holder stay. It is fastened to the end bracket by a plurality of bolts arranged at intervals in the circumferential direction, and a cylindrical cover made of an insulating material is fitted on the outside of the brush holder stay. The motor is further characterized in that the head of each bolt is covered by a part of the cover.
